COMBINED CLOVER THRASHING AND HULLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 255,097, dated March21, 1882.

Application filed July 18, 1881. (No model.) 7

To all whom it may concern:

Be it known that I, J. BENJAMIN BIRDsELL, of South Bend, county of St.Joseph, State of Indiana, have invented a new and useful Improvement inCombined Clover Thrashing and Hulling Machine; and I do declare thefollowing to he a full, clear, and exact description of the same, suchas will enable others skilled in the art to which it pertains to makeand use it, reference being bad to the accompanying drawing, which formsa part of this specification.

My invention consists of the combinations of devices and applianceshereinafter set forth, and more particularly pointed out in the claims.

The drawing is a side elevation of a combined clover thrashing andhulling machine, representing in dotted lines the interior operativemechanism.

A is the frame of the machine; B, its thrashing and 0 its hullingcylinder.

1) I) are any ordinary separating-bolts.

E is a tight board beneath the bolts, upon which the seed and chad drop,and it is so \'ibrated with a downward-and-forward movement that thesaid materials are constantly worked back and delivered at 6 upon thehulling-cylinder.

F is a traveling belt of raddles which draw the seed and chafl' as theyemerge from the liulling-cylinder up along the inclined floorf beneathand deliver it upon the sieves of the shoeeG.

H is the fan which cleans the seed in the ordinary way.

Iis the tailings spout,from which the tailings are delivered into anelevator, J, and are elevated, not, asheretofore,back into thethrashing-cylinder or upon the bolts, but up onto the tight board E,which directs them back through the hulling-cylinder without going againover the bolts. This is one of the essential features of my invention.It avoids the useless waste of power used to rebolt. It obviates theliability to clog up the bolts, and dispenses with what has heretoforebeen a useless operation upon the chaff and tailings.

S is a shaft, provided with projecting wire fingers of usual form,located over the bolt D in rear of the cylinder, which fingers preventany clogging at this point, and a winged shaft,

S, located in the hopper of the hulling cylin der, keeps the material atall times'feeding down upon the huller. The separators D D and the tightboard E are all of them agitated by the shaft T. Their respective cranksare arranged at thirds about the shaft, so as to give them countermovements, and thus neutralize to a great extent the usual shaking ofthe machine. Arms T T T unite the said cranks t 15 t respectively, withthe bolts D D and board E. The board E at its forward end is bentdownward, so as to leave room between it and the bolt D for a spiralconveyer, E, which delivers the tailings from the elevator across uponthe board E. This bent portion E of the board is provided with aserrated surface, so as more readily to feed the tailings backward andprevent them from dropping downward and forward by gravity.

At the rear end of the bolt D is a tight floor, U, beneath, and securedby side boards to the bolt D. The office of this tight floor is todirect such heads and chaff as may fall upon it forward to thehulling-cylinder.

I am aware that a clover thrashing and hulling machine has been providedwith devices for conveying tailings back to the huller after they havepassed through the same; and Ido not claim such construction broadly.

What 1 claim is- 1. In a combined clover thrasher and huller, thecombination,with the bolting devices and hulling mechanism, of the tightshaking floor under the bolts, arranged to carry the materials passedthrough the bolts to the huller, and the elevating and conveyingdevices, substantially as described,'arranged to take the tailings fromthe tailings-spout of the huller and deliver them upon said tight floorto be reconveyed to the huller.

2. In a combined clover thrasher and huller, the tight conveyingfloorhaving its outer end bowed downward, in combination with the huller, theelevator J, and the spiral conveyors I and E the latter of which isarranged over said bowed end of the conveying-floor, substantially asand for the purpose set forth.

In testimony whereof I sign this specification in the presence of twowitnesses.

J. BENJAMIN BIRDSELL.
